DATA TRANSMISSION METHOD AND SYSTEM

摘要

The present invention provides a data transmission method and system, wherein the method is used for a system framework using a virtual heterogeneous cell structure, wherein a macro base station covering a macro cell and a pico base station covering a pico cell share a same station address, and the method includes the following steps: according to the location information of user terminals, sending control information and data information to the user terminals of the macro cell and pico cell, enabling the user terminals to obtain the data information according to the control information. The system includes a sending module. The present invention implements the combined scheduling of the resource between the macro base station and the pico base station, reduces the interference between the cells and improves the total data rate maximally.
